[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a height adjusting structure provided on a waterproof flooring material having waterproofness such as a waterproof pan for a unit bath, a waterproof pan for a washing room, and a waterproof pan for a washroom.

[0002]

2. Description of the Related Art A conventional structure for adjusting the height of a waterproof flooring is shown in FIG.
As shown in the figure, a boss 2 protruding from the back surface 1a of the waterproof flooring 1
A nut 3 which is non-rotatably fitted into the recess 2a of the boss 2, a leg 4 composed of a bolt screwed into the nut 3 so as to be adjustable in height, and a locking nut 5 screwed to the leg 4. And a boss cap 6 externally fitted to the boss 2 for preventing the nut from falling off. In this height adjustment structure, on the back surface 1a side of the waterproof flooring 1, the leg 4 is rotated by a spanner to adjust the height.

[0003]

[Problems to be Solved by the Invention] By the way, waterproof flooring 1
There is a site surrounded by a building foundation or the like that is higher than the height of the waterproof flooring material 1 at the construction site where is installed. In a state where the waterproof flooring material 1 is installed close to the building foundation or the like, the waterproof flooring material 1
It is impossible to adjust the height by inserting a spanner on the back surface 1a side of the device. Therefore, each time the height adjustment is performed, it is necessary to raise the waterproof flooring 1 until it can be adjusted, which is very troublesome.

An object of the present invention is to provide a waterproof flooring height adjusting structure capable of adjusting the height from the upper surface of the waterproofing flooring while the waterproofing flooring is installed.

[0005]

Means adopted by the present invention include a boss protruding from the back surface of the waterproof flooring, a nut non-rotatably fitted into a recess of the boss, and a height equal to the height of the nut. In a height adjustment structure of a waterproof flooring provided with an adjustable threaded leg, the waterproof flooring has a through hole for rotating operation tool insertion which is open on the upper surface of the waterproof flooring and communicates with the nut. A sealing bolt, which is bored and seals the through hole, is removably screwed into the nut through the through hole from the upper surface of the waterproof flooring, and the leg member is connected to the upper end surface side for the pivoting operation tool. The height adjusting structure of the waterproof flooring is characterized in that the height adjusting structure is provided.

A locking male screw contacting the upper end surface of the leg is screwed into the nut, and the locking male screw has an insertion hole for inserting a rotary operating tool and is turned toward the upper end surface. A connecting part for a moving operation tool may be formed.

[0007]

When the waterproof floor material is installed at the construction site, the waterproof floor material is supported by the leg material on the construction floor surface. To adjust the height of the waterproof flooring, the sealing bolt is unscrewed to open a through hole for inserting the turning operation tool, and the turning operation tool is inserted into the through hole to connect the leg material to the turning operation tool. Then, the legs are adjusted up and down by operating the rotating operation tool. When the height adjustment is completed, a sealing bolt is screwed onto the nut to seal the through hole for inserting the rotating operation tool.

When a locking male screw is provided, the above-mentioned vertical adjustment is performed by inserting a rotating operation tool for rotating the leg material into the insertion hole of the locking male screw. After the up and down adjustment of the leg material is completed, the turning operation tool is inserted into the through hole and connected to the connecting portion for the turning operation tool of the locking male screw, and the turning operation tool is operated to lock the locking male screw in the locked state. Tighten.
